Biochemistry C785 WGU module 2 Questions
with Verified Correct Answers
amino group
Consists of hydorgen and nitrogen atoms (-NH3+)
carboxyl group
A -COOH group, found in organic acids.
R group
a functional group that defines a particular amino acid that makes it a specific protein (20
amino acids) aka side chain
alpha carbon
the central carbon atom of each amino acid
amino acid backbone
The structure comprised of the amino group, carboxyl group with a central alpha carbon
atom.
Hydrophobic
non polar, afraid of water
polar
Amino acid Molecule with partial charges. Mixes with water.
charged
Amino acid has a positive or negative charge
, Polypeptide
A single protein chain formed by amino acids bonded together
peptide bond
The chemical bond that forms between the carboxyl group of one amino acid and the amino
group of another amino acid by dehydration ( In which a water molecule is removed, C-N
bond)
Hydrolysis
Peptide bonds can be broken by this...A chemical process that splits a molecule by adding
water. ( this happened frequently in the stomach when proteins begin to bee digested into
their amino acids)
Residue
Remaining portion of amino acids after linked by peptide bonds ( how R groups get their
name)
N-terminus
the end of a polypeptide or protein that has a free amino group ( usually on the left)
C-terminus
the end of a polypeptide or protein that has a free carboxyl group ( usually on the right)
primary structure
sequence of amino acids in a polypeptide aka amino acid chain
secondary structure
